Tyre rolling resistance falls outside the scope of UN R0 because this attribute is used in the calculation of C02 emissions and IWVTA does not include UN R83 or UN R101.

UN R0 does not define or describe the family type (Type). Therefore, the first instance of an IWVTA should provide a type in order to establish the family type.

The Communication requirement of UN R0 follows that of the EC-WVTA and refers to the attachment of an information package. Germany proposes that this reference be replaced with an index of attachments referring to the relevant information document and test report(s).
